Canto 1 - Boyhood
Bāla-kāṇḍa
Chapter 36: Umā Curses the Demigods
Text 1.36.24

यस्मान्निवारिता चैव सङ्गतिः पुत्रकाम्यया।
अपत्यं स्वेषु दारेषु तस्मान्नोत्पादयिष्यथ॥

yasmān nivāritā caiva saṅgatiḥ putra-kāmyayā
apatyaṁ
sveṣu dāreṣu tasmān notpādayiṣyatha

yasmāt = because; nivāritā ca eva = was prevented by you; saṅgatiḥ = my union with my husband; putra-kāmyayā = for begetting a son; apatyam = sons; sveṣu dāreṣu = through your wives; tasmāt na = not; utpādayiṣyatha = you will be able to beget.

Because my union with my husband for begetting a son was prevented by you, you will not be able to beget sons through your wives.
